' -Tojall whom it v'nwy concern:

- a citizen of the United States,

.-' East Be it knownthat I, LAMAR'rms, Tnen'r,

State of California, have invented certain new and useful Improa'ements in Agitating and Aerating apparatus, of which the, fol-. lowing is-a speclfication. a

" p a The present, invention relates to an imdesignate-any suitable form of a receiving proved agitating, mixing and aerating appa ra'tus more particularly designed foruse in connection with the treatment of cyanidsolution'for the dissolving of. the gold containedtherein, although it is equally as well" adapted ,for the working'of any :class of solutions requiring agitation and aeration. To comprehendthe invention reference I should be had to the v accompanying Sheet of drawings, wherein v Figure l is a verticalsectional View of the apparatus. Fig. 2 is'a plan view. In thedrawings the numeral If is used to tank, into which the material"is delivered for treatment. .The said tank is preferably of, circular form, and provided with a tapering bottom portion 2. YVithin the tank '1 is mounted for rotation a vertically disposed tube 3, the lower end 37 of which is openfor the intake of. the'solution contained within the tank 1, while its upper end is-=closed by means of a plug 4, orotherwise; Fron the closed upper end of the tube 3 extends the shaft 4", which shaft works within the bearingii, and to the projecting end thereof is secured the gear 5,- with which gear meshes the pinion -6, on the drive shaft 6.

The centrally disposed tube 3 is supported from below by means of the bearing pin 7 which is stepped in the bearip g- 7 secured to the bottom of the receiving tank 1. Near its upper closed end, the centrally disposed tube 3 is provided with a series of outletsfor the escape of the material or solution entering the lower open end thereof; In thepresentcase these outlets are represented as a series of hollow radially-disposed arms 8, through which the material drawnby suction into the tube 3 is discharged under centrifugal stress.

Within the upper portion of the tube 3,

below the outlets thereof, is located a ball valve 8, which closes onto the seat 9, to prevent the'solution or material flowing ba ck- Wand into the receiving tank 1, afterhav ng been raised abovethe seat 9.

residing at Auburn, in the county, of Placer and I The material-discharged from the outlets or radially'disposed arms 8 impacts onto a circular grating or wall 9, secured within the upper portion of the receiving tank 1. The material is discharged from the outlets 8 under pressure, and strikes against the grating orwall 9 with suflicientforce to thoroughly breakup and scatter the discharge streams, so as to permit of air intermingling therewith to aerate "thesa'me and give actiwfity 'to the circulating solution,

which falls from the grating or wall 9" back into the body of solution within the tank 1.

ltiwill be understood that the tube 3 isro t'ated at a high rate of speed, being driven from the drive shaft 6 through the medium of the intermeshinglgear and pinion 5' and 6'.

Forthe treatment of the solution, the receiving tank '1, is filled approximately two thirds full, with the solution as a. single charge to be agitated, mixed and aerated,

-whe n rotation is imparted to-the centrally toward the outlet radially disposed arms '8,

from which the solution is dischargedunder centrifugal strains onto the grating or inclinedwall 9 with suflicient force to break which flow from the grating or inclinedwall 9 into the receiving tank 1 to intermix with the circulating body ofthe solutionwithin I the receiving tank. The dischargedstreams as thus broken by impact onto the Ming orwall 9, permit of air intermingling therewith to aerate. the solution.

,The solution is thus maintained in aconstant condition of agitation, throughout the up or scatter the jets or discharged streams,

working of the apparatus, the treatment being continued, where a eyanid solution is acted on, until all the gold contained therein is dissolved, when the working of the apparatus is discontinued, and the treated solution withdrawn from within the receiving tank. For this purpose there is shown an, outlet pipe 10, which, when opened, permits of the sohltion beingdrawn off.

Having thus, described the inventiomwhat pro- ' the same comprising a receiving tank or Yessel. an open lower ended centrally disposed tube rotatably held therein,'radially disposed outlets in the upper end portion of the said tube, and means for imparting rota-.

tion to the said tube to create a suction for drawing the solution into the lower open end thereof, and to force the same therefrom under pressure through the radial outlets. v

2. An apparatus for agitating solutions, the same comprising-a receiving tank or Yessel for theliquid to be treated, an open lower ended centrally-disposed tube rotatably held therein, radially disposed outlets in the upper portion of the tube, a valve interposed between's'aid outlets and the lower openend of the tube, and means forimparting rotation to the said tube to create a suction for drawing the solution into thelower open end thereof, and to force the same therefrom under pressur through the radial outlets.

3. An apparatus for the described purpose,.

the same comprising a receiving tank or vesset for the solution to be treated, an open lower ended centrally disposed tube rotatably held therein. a series of outlet arms radially extended from the upper portion of the tube for the discharge of solution enterin; therein, an inclined grating or wall within the upper portion of the receiving tank or vessel onto which the solution. discharged from the radial arms impinges, and means for imparting rotation to the central tube to create a suction for drawing the solution into the lower open end of the tube, and to force the same therefrom under pressure through the radially disposed outlet arms.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
